Does anyone have a programmer/chip on their first gen Tacoma?

Does anyone have their Tacoma chipped? Is it worth it and is there a notable difference in power or MPG? Looking at maybe doing it to my 04 and need opinions whether or not it's legit or a scam. Would like to add a little more HP and maybe some more MPG without breaking the bank. I'd love to get a supercharger, but don't have 4k laying around atm. Thanks fellas!

 

Ive read bad stuff. And good. I.say fuck it, supercharge that shit! I know i want to! Sorry this is of no help!!

 

They dont make chips for our trucks, sorry to burst your bubble.

Intake, headers and exhaust make the truck louder and smoother throttle response but add maybe 5 HP.

Supercharger and a 7th injector with ECU re tune is the only legit way to make power.

You could also do a Turbo setup but they are illegal in most states while the Supercharger is 100 bolt on 50 state legal.

If you want a fast truck buy a full-size with a V8.

 

This right here.

 

In all reality, i dont think ive EVER noticed a difference in 11 years with that button. I use it too, andi can't feel a difference.

 

He was joking

and that button is to hold the shift longer on auto's. use it when towing and your trans will keep from "hunting" gears

 

The only way to change the program on a gen 1 is to pull your ECU and send it off to have the chip set reflashed. The downside is that you wont have a running truck until you get it back

 

SKL Motorworks makes chips for our trucks actually. I have one. It definitely isn't going to give you much of any significant gains, but I will say what I do notice is smoother accelerating in high rpm's. I realize this is a super controversial topic and am in no way saying they are going to give you 20 extra hp and 20% better mpg like many claim, I am however saying that with the one I have on my truck I do notice SOMETHING (smoother acceleration in high rpm's).

 

If it plugs into the diagnostic or OBDII port on a Taco and isn't labeled Toyota TechStream it does nothing. Even if this device did have the intention of changing something, it couldn't as there are no values for it to change on a 1st gen Tacoma. I looked up that SKL brand, they sell snake oil adapters that plug into OBDII ports to fool the uninformed into believing that their vehicle's performance has changed. There are even some (from SKL) that claim to modify the signal from the MAF by having you tap into the wiring loom, but these only tap in with one wire and have no return wire to that specific loom. They are using the placebo effect to fool your butt dyno. They make one for everything, and they are all the same part. Please understand that I'm not making fun of you, I'm just pointing out that it is not possible for this "chip" to do
anything from the OBDII port or by "injecting" a different PWM signal to the MAF wire. Think about it, vehicles are complex and differ majorly, how could one part work for every vehicle?

Like mentioned above, the only thing for these trucks is an full EEPROM reprogram which is still rather pointless as it doesn't garner much in the world of gains, it is more to fix a broken ECU. The OBDII port is only for monitoring and diagnostics, there is nothing that can be edited through them unless you have a factory tool (even those don't edit the performance data, they just change things like door lock setting and beep codes).

For the later Tacos (2nd gens) they can be flashed from a Toyota TechStream for different (adjusted fuel map for supercharger) performance data.

 

Toyota would have to release their algorithm codes in order to access the ECU through the OBD2 port. To this day, Toyota refuses to release them. On newer Toyota trucks, essentially 05 and newer, companies have been able to alter the signal downstream of the ECU in order to make performance gains.

 

Very true. I'm not sure how much of a difference can be made downstream because the computer can only correct fuel maps and such by +or- 15% but yeah the theory is solid. Would certainly make correcting a real issue harder for the comp if it is already at its correction limit.

 

For example, Hypertech offers their Interceptor. Downstream they claim about 15hp on 87 octane and 17hp on premium. This is on the 07-newer Tundra so it is possible. Nothing great but possible. Nothing available for the Tacoma unfortunately other than speedo recalibration.

Not to thread jack, but for what it's worth i installed a Crawford eco block about 2 weeks ago. Haven't noticed much as far as power or MPG, but i have noticed when i go to pass on the freeway it doesn't hesitate as much when I step on the skinny pedal. It seems to be a wee bit torque-y-er to from a dead stop. Plus its only $50! Theres a huge thread on this site, look it up.

 

YUP! Well put. Thats basically exactly what I was trying to say!

 

Beauty about the ecoblock is it really seems to be backing its claims.lot of guys called it snake oil, then flipped there opinion when they saw actual results. You can even return the damn thing if you want. The company Crawford, i.e. Ken blocks Subaru builders has awesome customer service too. There planning to do dyno tests too.

 

I understand this is old but you said change the lock settings, does that mean that I can add keyless entry to the truck fairly easy? I already have power locks on my 02, just not keyless

 

I’m looking for more info on the eco block for my 2004 Tacoma. Part number maybe

 

A little nitrous oxide never hurt anyone either....

 

Right! It’s going to be a daily driver just doing small mods nothing crazy.. but I found the answer already. Q1 is the eco block 1st gen can use.

 

I imagine folks whose floorboards are rotted out can push the pedal further ehhhhhhhhh
